To all whom it may concern:

Be it known that I, LEWIS A. BUTTER- FIELD, a citizen of the United States of America, and resident of Chicopee, in the county of Hampden and State of Massa-- chusetts, have invented certain new anduseful Improvements in Fertilizer-Sowers, of," which the following is a full, clear, and exact description.

This invention relates to a. fertilizer d1stributer or sewer of; a class. comprising a hopper, having a revolublea-gitatortherein and which hopper has at the bottom there.- of two plates with apertures of. corresponding size and unifor'mlyspaced, oneof the .apertured plates being fixed, and serving as the bottom wall of. the hopper, while the other is slidable so as to leave the openings. of the full area or of only partial area, for

a time when the machine is moving to or away from the field there can be a cut-off by the last named plate without changing the adjustment of the second plate.

It is to be appreciated that after, under the exercise of more or less care, an adjustment of the second apertured plate relatively to the fixed apertured bottom wall or first plate has been effected, if then such second plate is slid to act as the cut-off, a careless or indifferent farm hand will not at all times take the'trouble to acquire the readjustment exactly as it had been before so that there may be a wasteful use of the fertilizer or a too scant distribution; and, therefore, by the additional independent apertured plate the latter may be used'as a cut-off without disturbing the adjustment of the second or regulator plate.

The invention is described in conjunction with the accompanying drawings and is defined in the claims.

In the drawings :Figure 1 represents a plan view of the fertilizer sower as seen inverted. Fig. 2 1s a rear elevation of the ma lines andj5 5, Fig,2. Fig. Gisa per spective 'viei'v'in representation'of the fixed, adjustable and cut-offplate at the bottom of the hopper",

' The hopper A isprovided as the body of a wheeled carriage, and it hasat; the bottom thereof the plate 64 provided with a plurality of space ddelivery openings a which are of diamond shape with rounded cornersor the shape of modified ellipses. This said plate forms the'fixed bottom of the hopper, the opposite sides ,of which latter are down wardlycom ergent; 6 represents the second plate. which is adjustably movable rela' 'ti'vely to the bottom forming plate. ahaving.

openings in spaced relation corresponding to those of the said plate a and. adapted to full or' partially register therewith according to the position at which it is adjusted. I

Said plate" bis to be regardedas the feed plate, or regulator of the quantityofthe fertilizer which may be .caused or' permitted toissue in a downward direction from the hopper. The third plate (Z is identical, practically, with the hopper-bottom forming plate a and the regulator plate I), the apertures 65 being of same size and having the same spaced relations as those a and b in the plates a and b. V

The plates 5 and (Z which are movable horizontally and endwise relatively to each other and to the hopper bottom-a, are held in their facewise relation by the guides or keeper-s 7 f of a characterheretofore usually employed in machines of this class.

The lowermost, cut-ofi plate (Z has its longitudinal movement imparted thereto by, a'

manually operable lever g pivoted at? on the side of the hopper and having an en- I gagement with the lug i whichis extended transversely beyond the edge of the plate.

The plate (Z is slightly shorter than the I 7 plates (Land-b, as is shown in Fig. 1; and

the'means for the movement of the plate 6 is shown to consist of the manually operable lever 7' pivoted at 76 on the side of the hopper near the middle thereof, and having connection by the link which is extended along parallel with the edges oflthe plates and has connection with the transversely extended lug Tn provided on the under side of the regulator plate at the end portion there'- of which is uncovered by the cut-off plate 03.

The provisions herein described and shown, in the fertilizer. distributing machine, additional to those which have been heretofore found in such machine, conduce greatly to the value of the machine and its capability for being employed for uniform and economical sowing; oi the fertilizer under any given adjustment of the regulator plate, and without the necessity of changing such adjustment (except as change thereof is desired and purposed) Waste of the material at time of going through or away from the field being insured by the. full 7 partially registertherewith, and having an angularly extended lug at one end thereof,

and acutofi 1: late,alsohaving openings in spaced relations corresponding to those of the bottom and the controlling plate in face- Wisecontaot against such plate, and adapted if according to the positioning thereof, to have its openingsin'registry with those of such:

plate, and tohave its openings entirely out of registry therewith, and terminating-at: one'end Within'the end oi the controlling plate, a lever pivotally mounted on an-inter-;

mediate part of thehopper, and having an adjustment imparting connection with :the cut oil plate,- another lever also 'pivotally mounted on [an intermediate. part of the hopper, and a link; connected to said'lever; extending" parallel With the said plates. and

9; extended raving. a connection .With'the lu from the end portion of the controlling plate.
